Which body organ is primarily affected by Hepatitis B Virus (HBV)?

Hepatitis B Virus (HBV) primarily targets the liver, leading to inflammation and potential damage. The liver plays a crucial role in various bodily functions, including metabolism, detoxification, and the production of proteins essential for blood clotting. When infected with HBV, the liver can become inflamed, which may lead to acute or chronic hepatitis, liver cirrhosis, and even hepatocellular carcinoma (liver cancer) in severe cases. This focus on the liver distinguishes hepatitis B from other viral infections that affect different organs, such as the heart, kidneys, or lungs. Understanding the specific impact of HBV on the liver highlights the importance of monitoring liver function in individuals diagnosed with this virus and emphasizes the need for vaccinations and preventative measures to mitigate its effects.
